How can the XML structure impact the effectiveness of XPath queries in PHP?

The XML structure can impact the effectiveness of XPath queries in PHP because if the XML is poorly structured or nested deeply, it can make it difficult to write accurate XPath queries. To solve this issue, it's important to carefully design the XML structure to make it easier to query specific elements using XPath. 

// Load the XML file
$xml = simplexml_load_file('data.xml');

// Example XPath query to retrieve specific elements
$elements = $xml->xpath('//parent/child/grandchild');

// Loop through the results
foreach ($elements as $element) {
    echo $element . "<br>";
}
